adding it wet to the clay slurry bucket is the
best way. most clay bodies have silica added anyway.
dry. pug..and it will never be noticed, just mixes
about 1 percent into a clay..... i always add old wet
glaze to my pug mill if the clay is too hard. lots of temmoku
went through my pug mill the last two years.
the other method is to
take scrap bisque bowls...fill them with glaze,
fire on the bottom back..under the shelves.
makes a solid glass mass.
throw it out. (or hand it in to the toxic tech guy..let him have it.)
(he will take it to the next flea market and sell them as found treasures.)
or, make tiles as hank suggests, send them to janet in wales.
i love to throw away old pots...we do it at the
farm all the time.
take them up into the woods....put them under logs.
into holes or swamp areas. think of the folks 2000 years from now..finding
them. it is important to leave ceramics for the coming ages.
and, i am convinced that a gallon of glaze would
be an ideal soil conditioner. hell, you could drink most stoneware
glazes and not be hurt at all. silica and clay...of course you
would not pooh for a month...kaopectate city.
glaze is very toxic to your lungs. not your stomach.
people just use the word `chemical`...and they think it will
kill you. a bit of common sense will rule the day.
think of what is in a glaze.
silica
feldspar
ball clay
china clay
iron
that is also a clay body. just reverse the materials.
and, they are all natural materials from nature, the ground.
the most common materials on this earth. toxic...i don't believe
it.
and yes, some folks use very exotic materials in glaze...well then,
they would know that, and take care of it properly.

in the case of old hopkins high, the expert on hazardous materials
was the number two janitor and he almost graduated from
high school. boy, he was a real expert alright.
if you believe that...i have a some thousand dollar pots i want to
sell you. but, he thought he had the power of god.
`mel, what is in this bucket?` `well, if i told you, would you understand?`
no. `then get the hell out of my room you ass.`

Mel (or anyone),
What if the glaze has lead in it? I inherited a number of dry glaze
materials that belonged to my mother who was a part time potter.
Reading her notebooks, I found that most of her glazes contained lead
(including Tizzy glazes). There is a couple of pounds of white lead
and about 30 lbs. of mixed dry glazes with unknown ingredients
(probably including lead). I don't want to fire them in my kiln for
fear of contamination. What's the best way to safely get rid of these
materials?

Contact your local government and ask when hazardous collection material
days are. Many more localities are scheduling special times when they will
accept solvents, paints, batteries and the like. Not certain what the
policies might be for lead, but you could ask.

Hi Leesh,
Most communities in the U.S. have a once or twice a year opportunity
to get rid of hazardous materials by taking them to some collection
point. That is where you can get rid of insecticides or lead-
containing paints, etc--anything that should not go in the landfill.
Mine even takes old computer monitors and stuff like that. I would
call my local town or county office and ask if your community has
such an event.
Regards,
John

Thanks John and Bill,
I'll check for the local toxic dump days.
